Construction crews working near the exit ramp for Paramus Road off the westbound highway accidentally punctured the 16-inch main shortly before noon Aug. 17.
It unleashed a mini flood that filled the exit with nearly a foot of water and closed Route 4's left lane near the median.
A crew from Veolia got to work while Paramus police and a state DOT team did their best to keep traffic moving past the spot.
Boyd A. Loving took the photos and contributed to this story.
